Lexmark's Z2490 WiFi printer can be connected to a wireless network and the computers connected to that network can print from it without needing to connect via a wired Ethernet connection. This allows you to print from a laptop with wireless capabilities, such as the Dell Inspiron 1525 Notebook. The Lexmark software has to be installed first.
1). Click on the Network icon (it looks like a computer or group of bars) in the lower-right corner of your desktop. Click on the network with the Lexmark printer on it, then click "Connect."
